This file contains instructions on how to install the cp/m 2.2 operation system on my 8080 SBC.
Also descriptions of files in archive are given. If you have any questions, feel free to contact me.

Files descriptions:
*.asm	-	source code (generic assembler) 
	I have put a lot of effort to remove all macros  from digital research sources.
	Now you can use generic assembler without support of macros and librarys.
*.hex	-	generic intel HEX (to load via COM port)

bootsec	-	bootsector OS loader (must be on track 00, sector 01)
wrsys	-	transfer OS and bootsector to system track 00 (whole track 00 reserved)
cbios	-	custom BIOS for 8080 SBC
cpm22	-	cp/m 2.2 OS
kermit	-	file transfer utility (check for manual ftp://kermit.columbia.edu/kermit/a/cpkerm.txt)


How to install CP/M on new hard drive:
	To install the CP/M 2.2, you must use the "monitor" command 'R' to load the following files into
	the RAM in this order:
wrsys.hex
bootsect.hex
cpm22.hex
cbios.hex

It will take a few minutes at 9600bps. Now execute 'wrsys' by entering 'J100' "monitor" command to transfer
system image from RAM to HDD system track. After few seconds job was done and system will halt.
Reset SBC and try to use 'B' command. You will see CP/M booting message and command promt.

How to transfer files to/from CP/M disk:

	Perhaps you want to write the files of transient commands or other files to disk.
To write files to CP/M disk, you first need to rtansfer the kermit program.
Boot CP/M from monitor, then reset to "monitor" and load "kermit.hex". Now you have both CP/M and kermit in RAM.
Execute kermit program by entering 'J100'. After kermit's prompting, type command 'SET PORT TTY' to setup COM port for transfer.
Type 'R' command to receive files from host. First, forward the file "kermit.com".At the same time, you can transfer multiple files.
I'm use ZOC Terminal, it can handle kermit protocol (https://www.emtec.com/zoc/), but you may use any other terminal's wich support
kermit protocol.


Version info:
	It's v0.1 beta. Only one 8Mb disk drive A: support.
